There's a lot of buzz about virtual desktop infrastructure and what it can offer companies in terms of productivity, cost savings and data security. So much buzz, in fact, that you might wonder if the desktop, notebook or tablet you're reading this on is about to become extinct. As Knowledge Center contributor Jeff Nessen explains here, the answer is maybe.
There will always be a
need for conventional desktops and notebooks for specific users, but desktop
virtualization has matured today. In fact, it's time to take a hard look, not
just a passing glance, at what it can provide.
The magic that virtual desktop infrastructure (VDI) can provide is in
taking a fairly inexpensive thin-client device, giving it access to your data
center from anywhere, and allowing that device to take on the image of a
typical desktop. VDI provides the device with all the data and applications you
need throughout your day, and then reverts to the proverbial tabula rasa when
you shut it down. Because no data is stored on the device, you never have to
worry about proprietary data falling into the wrong hands if the device
itself-desktop, laptop or tablet-is lost or stolen.
VDI should change the way you think about the desktop. For your users
who fit the bill, there are significant reasons why VDI makes sense right now.
Five reasons to examine VDI now
No. 1: Hard cost savings
Thin clients cost less and they last longer
(six to seven years versus four years for a notebook). They also consume a
fraction of the energy of a desktop PC (as low as six to seven watts for thin
clients versus 150 watts for PCs).
No. 2: Ease of management
Thin clients are easier to patch and
upgrade. They have slower generational changes than PCs so you're not swapping
out newer versions all the time.
No. 3: Centralized backups
When using virtual desktops, everything is
backed up centrally, which is easier on data center operations and eliminates
local drive issues. This makes sense for tablets as well since they are not a
traditional client device and their backups most certainly are not handled by
most enterprise backup applications.
No. 4: Regulatory compliance
Since all the data and applications are
centralized, VDI makes it vastly easier to enable and enforce processes and
procedures to ensure security, privacy and other best practices.
No. 5: Productivity gains
VDI encourages telecommuting or remote
working, which can contribute to higher productivity, better morale and lower
office space expenses while decreasing demands on help desks. If there are
problems, it's easier to troubleshoot standard images and integrate
applications with standard hardware. Plus, users need less training with
While these reasons to
examine VDI now are substantial and worth considering, VDI isn't for everyone-at
least not yet. To be successful, you need to be very selective with the users
you choose to bring into the VDI model. But for those users that can take
advantage of VDI, the benefits they reap may feel a bit like magic.
